The original method using single-primer extension was inefficient due to a low yield of mutants. This resulting mixture contains both the original unmutated template as well as the mutant strand, producing a mixed population of mutant and non-mutant progenies. Furthermore, the template used is methylated while the mutant strand is unmethylated, and the mutants may be counter-selected … WebThe QuikChange Multi site-directed mutagenesis system is a novel technology that allows mutagenesis at multiple sites in a single round, using a single oligonucleotide per site.
